Same happens to me. I have an HP 6730s Laptop with the following specs:
CPU: Intel® Core™2 Duo CPU T5670 @ 1.80GHz × 2
Mem: 2GB
Graphics: Mobile Intel® GM45 Express Chipset
OS: Linux Mint 12 (Lisa) - 64-bit
HDD: 160GB
It does get annoying having the mouse freeze at random times. I haven't tried using an external USB mouse.
